Abstract
A high-integrity electromechanical actuator control system includes a system function controller, a plurality of actuator controllers, and at least one electromechanical actuator. Each actuator controller includes a first controller, a second controller, and a duty cycle computation circuit. The first controller receives digital actuator control commands supplied from two of the function control channels and supplies first digital duty cycle commands. The second controller receives digital actuator control commands supplied from two function control channels and supplies second digital duty cycle commands. The duty cycle computation circuit receives the first digital duty cycle commands and the second digital duty cycle commands, computes an average of the first and second duty cycle commands, and generates pulse width modulated (PWM) commutation control signals based on the computed average.
